To all whom it may concern:

Be it known that I, EUGENE H; TAYLOR, a

. citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented a certain new i and useful Improvement in Methods of Making Paper Boxes, of which the following is a specification, reference being had therein to the accompanying drawings. My invention rovides a new and improved method. of ma 'ng boxes of that kind in which pieces of gummed paper known as stay strips are employed to secure together the corners of; the pieces of cardboard composing the boxes.

The invention is applicable to boxes which are made from a single blank of cardboard or other suitable material, having the corners cut or dled out, and which are scored, creased -or wetted along the lines which forinthe outside periphery of the bottom of the box; also to boxes which are made up of three pieces and are known as end set boxes, as well as to covers and to other forms of boxes.

The improved method of making boxes consists in applying successively instead of simultaneously as has heretofore been one tomary the two halves of the pieces of stay strip required to stay the box to the appro priate portions of the box blank or pieces of cardboard composing the boxes.

This method enables the boxes to be made much more rapidly since it permits the four stay strips for the four corners of the box to be applied to the box blank simultaneously, while the blank is in aflat condition, instead of succcssively after the blank has been formed, as

'die and beneaththe upper die and a piece of stay strip is then placed in proper position on the appropriate portions of the box. The

upper die is then caused to descend, and both sides of the said stay strips are thus iirmly attached to the appropriate portions of the box, and the corner of the box is thus com- 'pleted. The operator then turns the box so that, il 1; next corner of the box is in position between the dies, and repeats the operation. This is done for each of the corners-of the box so that the four corners are stayed successively, but both the sides or halves'of any single piece oi stay styip are simultaneously attached to the box. In my improved method ol' manufacturing a box. one-half of the pieces of stay strip for each corner of the box is simultaneously applied to its proper )lace on the box blank. Then the box blank is folded to proper form and the unattached portions of the pieces of stay strip are bent about the corners of the box and attached in proper position. By this improved method, I am enabled to attach the first halves of the four stay strips to the four proper portions of the box blank simultaneously and at one operation, and then by a second operation, after the box has been folded, to attach the unattached halves of the four pieces of stay strip to their proper portions of the box blank. In this manner the period'of pressure which is re uired to alllx the stay strip to the material til which the box is composed is halved, because in my improved process, 'there are only two periods of pressure, whereas in the process heretofore employed, there are four such periods, one for each corner. Furthermore, the time required to turn the box from one position to another to bring the corners successively in position between the dies is entirely eliminated.

In the drawings,l igure 1 is a plan view of a flat blank with. corners died out and having attached to the corners thereof pieces of stay strip. Fig. 2 is a view in perspective of the same box blank, the sides and ends thereof being folded up into osition to form a box and showing the hal attached pieces of stay strip before they are turned about the corner of the blank and attached thereto. Fig. 3 shows the completed box. Fig. 4 shows the blanks and half attached stay strips for the construction of a box composed of independent bottom, end and side pieces.

Referring to the blank is indicated by A. and portions B B, andside pieces C C, the

said side flaps an (1 end. portions being ad apted to be folded up along the dotted lines E which may be scored, creased or wet, so that the stock will fold more easily to form a box. In. carrying out my process, I ply pieces of stay strip F to the side or end -flaps B and (J. In Fig. 1 I have shown the said pieces of stay strip as applied to the side pieces 0, and

drawings,-the boxlt is provided with find it convenient in practice to apply them to this part of the blank, because it permits the stap strip material to be fed from parallel rolls. Stay strip material may be provided preferably with adhesive material in the wellknown fashion, in which case the said adhesive is wetted to cause it to adhere to the material composing the box blank. It is subjected to sutlicient pressure to unite it to the box blank. The four pieces of stay strips F are simultaneously placed upon the body blank, so that the hall (1 in each case falls upon the proper portion ol the. body blank and adheres thereto, whereas the part It projects therefrom. in practice I find it convenient to make the. parts G and H substantially equal in size. After the four pieces F of stay strip have been attached to the body blank A as shown in Fig. 1, the body blank is formed by folding up the end and side tlaps B and t) as shown in Fig. 2 along creased or scored lines E which form the bottom edges of the box. The unat- .t-aehed portions H of the stay strip F are then simultaneously folded about the corners of the box and attached to the body by means oi the adhesive on them by suitable pressure exerted upon them. The box is then in the 'linished i'orm shown in. Fig. 3 where the stay strips 1* are shown as folded about the corners of the box, and attached thereto.

ln Fig. 4 1 have shown the blanks and partly attached stay strips for a box, composed oi separate bottom, end and side pieces.

Attached to the bottom are the pieces of stay strip J, K, L and M by means of which the end pieces 0 and P and side pieces Q and R are attached to the bottom blank I. Pieces of stay strip S, T, U and V are also 0 provided to secure together the adjacent edges of the end and side pieces after the body blank has been formed. As has been explained above, my process is also applicable to other kinds of boxes and to covers, but I '45 have thought the forms shown suflicient for the illustration of my improved process.

NVhat 1 claim. is:

1. The improved method of making paper boxes which consists in simultaneously at- 5 taching' to the appropriate portions of the material for a box a portion of a piece of stay strip for each corner of the box, forming the box, and then simultaneously attaching the previously unattached portions of said pieces 5 5 of stay strip.

2. The improved method of making paper boxes which consists in simultaneously attaching to the appropriate portions of the material tor a box when in a flat condition a 60 portion of a piece of stay strip for each corner ot the box, formingthe box, and then simultaneously attaching the previously unat tached portions of said pieces of stay strip.

in testimony whereof I atlilx my signature, 65 in presence of two witnesses.
